Luis Collazo, fighting in his hometown of Brooklyn, knocked out Victor Ortiz at the end of the second round in an early and stunning end to their welterweight fight at Barclays Center Thursday night.

Ortiz was fighting for the first time since breaking his jaw 19 months ago. He came out aggressively in the first round, but was caught by a hard right hook from Collazo with one second remaining in the second round.

Collazo had pushed the action in the second round, and was winning the round when he caught Ortiz on a counter right hook.

Ortiz (29-5-2, 22 KOs), a former welterweight champion, was unable to beat the 10 count, and lost for the third consecutive time, clouding his future as an elite fighter. He was stopped in each of the three losses, including a fourth-round knockout by Floyd Mayweather and a ninth-round stoppage by Josesito Lopez, who broke Ortiz's jaw earlier in the fight at Staples Center in Los Angeles in 2012.

Collazo, 32, also a former welterweight champ but considered more recently as more of a journeyman, cried after Ortiz was counted out.

"I had no doubt in my mind that I was going to win," said Collazo. "I went through hard times and maybe I wasn't ready before, but I was ready today.

"Coming into this ring, I was excited. performing in Brooklyn in front of all my fans, in front of people I grew up with. To represent from the Borough of Brooklyn, I'm just stoked," Collazo (35-5, 18 KOs) said. "I'm excited man."

Collazo, who has won four fights in a row, said he was able to see Ortiz's punches coming.

"I knew he was going to come out aggressive, that's the type of fighter he is. I just wanted to stay on my gameplan, and see where he came from. I was seeing the shots coming wide open."

Just before the knockout punch, Ortiz, like Collazo a southpaw, threw a sweeping right hook that missed and Collazo countered with his short right hook that put Ortiz down.

"I'm not a big puncher, but a hook on a hooker is deadly," Collazo said. "It was nice and short. Boom! A lot of people say I can't punch, but I don't know."

Asked who he wanted next, Collazo said, "I want what the fans want. I want Floyd (Mayweather) here in New York. I'm tired of going to Vegas, Floyd, come here to New York and fight me."

On the undercard, televised by Fox Sports 1, in a battle of undefeated up-and-coming 21-year-olds, Eddie Gomez from The Bronx knocked Daquan Arnett from the unbeaten ranks, winning a unanimous 10-round light middleweight decision.

Gomez (16-0, 10 KOs), dictated the tempo most of the way, mixing body shots in with his frequent combinations. Gomez used one of those body shots to put Arnett (11-1, 7 KOs) on the canvas in the 7th round. Gomez won comfortably by all three judges, 97-92 twice and 98-91.

Gomez landed 154 punches to Arnett's 99.

"I should have gone to the body earlier and I think I could have gotten him in four or five rounds. I'm just thankful for the opportunity to get this fight. I took full advantage and worked hard."

Also, former Olympian Gary Russell Jr. upped his record to 24-0 (14 KOs) with a fourth-round technical knockout against overmatched opponent Miguel Tamayo.
